So W was slowly starting to change, she was still the same person but her sexual desires were being changed by a dark interest in being seen as a dirty slut, this seemed to arouse her. The night of the BBQ we went home and she initiated sex in the lounge, we are not prudes but it is usually in the bedroom that sex takes place, she seemed a bit more aroused, a bit more horny than normal, as I was fucking her I was looking into her eyes and I asked her was she turned on by that thug from earlier saying he wanted to fuck her, she hesitated and then cautiously said yes, she told me she was still mine but she liked the idea of sex being a bit different, a bit wilder, a bit more spontaneous, she was used to being in control and respected she liked the idea of someone just using her to get their rocks off and her not being in control, she liked the idea of a much younger man using her. I didn’t mind all of this, we had never spoken like this before but it had made me harder, I kissed her and said be careful what you wish for. W went away on business for a few days shortly afterwards, leaving me alone at home, I was used to this, one evening whilst watching the TV I scrolled through my phone and found the number of that thug from the BBQ, I sat looking at it for a while and then thought why not call him and see if I could fix something up. I phoned the number and a female voice answered, she sounded a little upset, I apologised for calling out of the blue and explained who I was she remembered me from the BBQ. I asked if he was there, I didn’t even know his name, turns out it was Dan, the girl on the phone, her name is Emily explained he always leaves his phone at home when he is off fucking someone else, she came home from work and found his phone and a note saying he wouldn’t be back until late. We had a chat and I explained everything about what he had said to W and the effect it had on her, Emily wasn’t surprised. So I wasn’t sure how the next bit of my plan was going to go but I just came out with it and said I wanted to ask him if he would come to our house meet W again but this time and with my blessing fulfil her obsession with being used like a dirty slut, but I added W knows nothing about this. Emily then made a further suggestion which I agreed to subject to everything else being well received, she said she would speak to him and let me know….. a few days later I had a text from an unknown number it turned out to be Emily, she said Dan was up for it and that they would see us the following week. When W returned from her work trip I told her I had arranged a surprise party for her the following week, I explained although the party isn’t a surprise the other guests are. The week went slowly as I was waiting for the night to arrive, W had been out an bought a new outfit, I encouraged her to be a bit more risqué in choice, to expose some well tanned boob, she asked who was coming countless times but I wouldn’t tell her. The day of the party arrived and W had taken the day off of work to relax and get ready, she had a gym session, a massage and then her usual beauty treatments, she had bought a new dress but as usual with her it was classy although I will admit more risqué than usual, but on the basis that she was going to be used by the arrogant thug it was too classy. Our guests were due to arrive at 7:30 everything was ready, drinks, a bit of food, the scene was set…… The doorbell went, W asked me to get the door I did knowing full well who would be there, I opened the door to be greeted by Emily she was dressed to impressive and her fake boobs were really looking good, she held out a bottle of wine and then stood behind her was Dan, looking confident and full of himself, I asked them in we walked down the hall and into the lounge W was waiting as we entered and she saw Dan first then Emily and then me she asked what they were doing here, Emily said they had been invited to our house party because when she last met them, Dan had made a large impression on W, W went a little red and glared at me, she said have I been set up. At this point Dan walked up to her slapped her backside and said looks like we are going to have some fun tonight, I need a drink. Things were a little awkward for a while, whilst Emily was very nice, engaging and friendly, Dan wasn’t interested in conversation he just sat there drinking his beer. This was going to take a while for W to relax knowing what was in store for her later, she had been set up but was taking it with good grace and although she and I were just over 20 years older than Emily and Dan she seemed to be enjoying the conversation, there were times when Dan and Emily ratcheted up the atmosphere and char some of it was a little crude, and to my surprise Emily was possibly worse than Dan, they had been with us nearly an hour or so and then Dan said right are we going to get on with it then ? Everyone was a little taken a back, W looked surprised how quick this was all going to change, Dan stood up looked at me and Emily and told us to fuck off in the garden whilst he warmed W up, W smiled politely and told us to go. Emily and I took our drinks and went into the garden, we both knew full well that Dan was going to mauling all over W anytime soon. W later told me as soon as we left the room he grabbed her told her she was his and that he was going to fuck her senseless, she said at this point she went weak at the knees and he kissed her, his tongue was in her mouth we was pulling her hair back and kissing her neck whilst grabbing her arse and groping her boobs, W has a large pair and he was telling her how he was going to get a tit wank off of her later, W wasn’t exactly sure what that was, her nerves started to easy and she got into the flow of things, she even ventured to grab his groin, he felt big. After 20 minutes or so Emily said we should go back in, gods knows what the animal will be up to with your missus by now. We walked back in and W was straddling him on the sofa, they were kissing passionately his shirt was open showing his ripped body and W’s dress had risen up to reveal a thong clad arse with stockings, his big hands were mauling her, they hardly noticed us, we sat down on the other sofa and watched. He soon became aware we were back as he broke off the kissing, told W to stand and then he told her to strip to her lingerie and give us all a show. W seemed empowered and looking around the room started to undress, here was my successful business woman wife stripping in front of a thug and his girlfriend and me, she seemed to have changed, she didn’t care that she would be soon stood in a room semi naked. She stripped to her lingerie, Dan told her to go over to our sofa and wiggle her arse and boobs in our faces, she walked over wobbling in her heels and leant forward to Emily and thrust her boobs in Emily’s direction, Emily touched them through the bra, W then stood in front of me turned around and bent down to hold her ankles her thong clad arse right in front of me I reached out to touch it but Dan told me she wasn’t mine and only he was allowed to touch her. Then he told her to walk back to him, she did, he told her to kneel and then he stood up unbuckled his trousers and dropped them and his boxers to the floor his massive cock sprang out in front of W, it must have been 8 inches and thick, he was cut. He took his belt form his trousers and proceeded to fasten it around W’s neck, he told her to put her hands behind her back and open her mouth, she did and then without warning he thrust his cock into her mouth pulled on the back of her head and she involuntarily swallowed him whole, she gagged and chocked but he didn’t care, he released her then sat down and told her to blow him, she looked over her shoulder at me, I nodded approval and she went to work, W gives good head but this was different it wasn’t gentle it was animal like and he was talking to her the whole time telling her how dirty she was and how he loved fucking older married women as they are so grateful to get the mouths around young meat. She blew him for a while then he pulled her be the hair, saliva ran from her mouth down onto her boobs he kissed her roughly her lipstick smearing over her face, then he told her to remove her bra which she did, he tightened the belt around her neck a little and said stick this between your boobs and wank me, W had never done this before she pushed them together either side his cock and then moved them up and down, she looked unsure he told her she learnt quick and that he thought she wasn’t as innocent as she made out, he accused her of fucking her business clients and that really she was just an easy slut, she barked back at him no, for that he jerked the belt a bit tighter, his cock was oozing pre cum on her boobs, he told her to stop and that he wanted to mark his territory with that he put his mouth to each boob on turn and then left a massive love bite on each, she had never had these before. I was getting turned on watching, Emily was squirming in the sofa next to me then this quite girl who obviously had put up with a lot from him, stood told him he wasn’t the only one who could get their rocks off and then proceeded to drop her dress to the floor, she was only standing in a thong and high heels her fake boobs looked massive against her small frame, she turned to me and said use me, fuck me just like he is doing to your wife, with that she thrust her boobs into my face, W looked at me. This was the surprise Emily and I had in store for Dan, W could hardly protest she had just blown a 23 year old and had two love bites on her boobs, in next to no time I was naked and as opposed to Dan who was fucking my wife I was making love to Emily, it was much more tender but as she was so young it felt so good her body was heaven and she gave good head as I sat there watching Dan maul my wife, but then my wife was loving it, Dan seemed to lose a bit of arrogance, but he was still treating my wife like a fuck toy, he shed all his clothes took the belt that was around her neck and led her to the other end of the lounge told her to drop her thong and spread her cunt, my wife didn’t like this word but did as she was told, she lay back in the sofa spread her legs and said lick my cunt make me cum you bastard, Dan was on his knees and at her cunt like a man possessed, it wasn’t long before W came, when she comes she can be noisy today she was more than normal. Seeing this Emily had me between her legs licking her out, she encouraged me to finger her, she was bald, W had always had a bush of hair, but this was so good, I was a convert. After a while I told Dan I was going to fuck his woman, I picked her up carried her over to the sofa and put her down next to W and spread her legs, I then positioned my cock at the entrance to her pussy and slid in, Emily moaned in appreciation, not to be out done Dan flipped W over onto her belly, her knees on the floor and entered her from behind, both of us were bareback in each others girls, this was becoming like a competition who could out do who, he then took it up a level, W had her face close to Emily’s massive boob, he pulled the belt still around her neck, pulled her hair and thrust W’s mouth over Emily’s nipple and told her to suck on it, W tried to pull away she always told me she wasn’t in anyway bi, but she had no choice he wouldn’t let go. So my wife is being fucked by a 23 year old whilst sucking his girlfriends boob and I am fucking the girlfriend. We all fuck for what seems like ages, I am the first to reach the point of no return and tell Emily I am going to cum, she says shoot over my belly and tits, I do I have always been a heavy cummer, and don’t disappoint, next Dan announces he has lasted longer fucking the tight cunt of the posh bird and is going to cum, confirming her descent into being a slut W tells him to cum in her, he pulls the belt even tighter, pulls her head back and shoots his load deep into my wife. We all slump back for a bit taking in the events of the last hour or so, W had cum in her and love bites, Emily had cum on her boobs and belly, Dan told W to lick Emily clean, W had never tasted my cum like this before but did as she was told. We then stopped for drinks all naked and basking in the glow of a sex session from heaven. Shortly afterwards, Dan said they were going, W thanked him and Emily for a great evening, and asked if she was now a true slut, to which Emily replied yes and added thanks for letting me fuck your husband he was great. Dan then said as they got to the door, if W was interested he was having a lads night at one of his friends in a few weeks and they were trying to arrange for two older women to be used for the night, six blokes two sluts, he said if W was interested then to let him know but she would be perfect. The door closed a naked W turned to me and said that was fucking amazing thank you for letting me be free, I said she was the perfect slut and could be the businesswoman by day and slut by night, she did go to Dan’s party but that is another story.
